Here, we determined the complete mitogenome of , as the first representative for the subfamily Podopinae. This mitogenome is 15,633 bp long and contains 37 typical mitochondrial genes. The genome size, gene arrangement, A + T content, codon usage and secondary structures of 22 tRNAs of the mitogenome were similar to that of other sequenced pentatomoids. This mitogenome exhibited a reverse nucleotide strand bias, i.e. positive GC-skew (0.021) and negative AT-skew (-0.086). Phylogenetic analyses based on mitogenomic data strongly supported the monophyly of each of the five superfamilies within Pentatomomorpha and recognized a phylogeny of (Aradoidea + (Pentatomoidea + (Lygaeoidea + (Pyrrhocoroidea + Coreoidea)))). However, clustered with three Pentatominae species, suggesting that Pentatominae probably was not monophyletic, or Podopinae may not be a valid taxonomic group. The mitogenome sequence of could contribute for better understanding of population genetics and evolution of this insect pest.
在此，我们测定了 的完整线粒体基因组，作为豆蝽亚科的首个代表。该线粒体基因组长度为15,633 bp，包含37个典型的线粒体基因。该线粒体基因组的基因组大小、基因排列、A+T含量、密码子使用情况以及22个tRNA的二级结构与其他已测序的蝽类相似。该线粒体基因组呈现出反向核苷酸链偏向性，即正向GC偏斜（0.021）和负向AT偏斜（-0.086）。基于线粒体基因组数据的系统发育分析有力地支持了半翅目五个超科各自的单系性，并识别出一个（蛛蝽超科 + （蝽超科 + （长蝽超科 + （红蝽超科 + 缘蝽超科））））的系统发育关系。然而， 与三个蝽亚科物种聚类在一起，这表明蝽亚科可能不是单系的，或者豆蝽亚科可能不是一个有效的分类群。 的线粒体基因组序列有助于更好地理解这种害虫的群体遗传学和进化。
